I really like the speedbar feature because it facilitates setup and any user adjustments to the stat after installation. The three were retrofits for three older digital stats. Installation was easy and the installer/user configuration was a snap. Of the three that were purchased one had a bad backlight.

This was the exact thermostat I was looking for at a good price. It has the potential for 4 heating stages as well as two cooling. I'm using it with a geothermal heat pump so the first two heating stages work with the heat pump only, the third works a combination heat pump and backup electric heat, and the fourth works the backup electric heat only if the geothermal field goes down. It also has settable differentials so you can have the different stages of heating/cooling fire up and the temperature swing you determine.
